Extractions: Hypatia Of Alexandria Hypatia was born in the year 370, in Alexandria, Egypt, and died March, 415, in Alexandria, Egypt. She was the first woman to make a substantial contribution to the development of mathematics. Hypatia was the daughter of the mathematician and philosopher Theon of Alexandria and it is fairly certain that she studied mathematics under the guidance of her father. Hypatia became head of the Platonist school in Alexandria in about 400 AD. There she taught mathematics and philosophy, particularly teaching the philosophy of Neoplatonism. Hypatia based her teachings on those of Plotinus, the founder of Neoplatonism, and Iamblichus who was the developer of Neoplatonism around 300 AD. Hypatia came to symbolize learning and science which the early Christians identified with paganism. However, among the students who she taught in Alexandria there were many prominent Christians, One of the most famous is Synesius of Cyrene, who was later to become the Bishop of Ptolemais. Many of the letters that Synesius wrote to Hypatia have been preserved and we see someone who was filled with admiration and reverence for Hypatias learning and scientific abilities. In 412, Cyril (later St Cyril) became patriarch of Alexandria. However, the Roman prefect of Alexandria was Prestes, and Cyril and Orestes became bitter rivals as church and state fought for control. Hypatia was a friend of Orestes and this , together with prejudice against her philosophical views which were seen by Christians to be pagen, led to Hypatia becoming the focal point of riots between Christians and non-Christians.

Extractions: (fl. c. 300-c. 350) Very little is known of Pappus' life. Moreover, very little is known of what his actual contributions were. We do know that he recorded in one of his commentaries on the Almagest that he observed a solar eclipse on October 18, 320. He is regarded, though, as the last great mathematician of the Helenistic Age. He wrote The Collection or The Synagogue , a treatise on geometry which we discuss here and several commentaries, now all lost except for some fragments in Greek or Arabic. One of the commentaries, we note from Proclus, was on The Elements Note that higher geometry was in complete abeyance until Pappus. From his descriptions, we may surmise that either the classical works were lost or forgotten. His task is to `restore' geometry to a place of significance. Basically, The Collection or The Synagogue is a treatise on Geometry, which included everything of interest to him. Whatever explanations or supplements to the works of the great geometers seemed to him necessary, he formulated them as lemmas. Features: It is very broad, designed to revive classical geometry.

It's an extraordinary story and here to tell it is Maths Lecturer from Monash, Dr Michael Deakin. Dr Deakin: Imagine a time when the world's greatest living mathematician was a woman, indeed a physically beautiful woman, and a woman who was simultaneously the world's leading astronomer. And imagine that she conducted her life and her professional work in a city as turbulent and troubled as Ayodhya or Amritsar, Belfast or Beirut is today. And imagine such a female mathematician achieving fame not only in her specialist field, but also as a philosopher and religious thinker, who attracted a large popular following. And imagine her as a virgin martyr killed, not for her Christianity, but by Christians because she was not one of them. And imagine that the guilt of her death was widely whispered to lie at the door of one of Christianity's most honoured and significant saints. Would we not expect to have heard of all this? Would it not be shouted from the rooftops? Would it not be possible to walk into any bookstore and buy a biography of this woman? Would not her life be common knowledge?

Extractions: The faculty and staff of Cherry Hill Seminary, named Hypatia of Alexandria as the Seminary's guardian ancestor. Hypatia was a pagan, a woman, a martyr, and most importantly, a scholar. Born in 370 CE in Egypt, she was considered both eastern and western: She flourished and taught in the Mediterranean area and was fed by rivers of learning from all the civilizations in the mid-east. Hypatia was one of the mothers of our western traditions and embodied the scholarly riches of diverse cultures. Described by her contemporaries as a charismatic teacher, Hypatia was later murdered by a mob of zealous Christians in 415 CE. The formal name adopted is Despoina Hypatia Polumathes. Despoina is "Lady, Mistress"; Polumathes means "much-learned." She as consecrated as our guardian ancestor at Cherry Hill's intensive on June 10-12, 2004, in Vermont.

The Beginnings Of Trigonometry According to theon of alexandria, who worked in Alexandria as a teacher ofmathematics and astronomy, Hipparchus wrote a treatise in twelve books on chords http://www.math.rutgers.edu/~cherlin/History/Papers2000/hunt.html
Extractions: Rutgers, Spring 2000 The ancient Greeks transformed trigonometry into an ordered science. Astronomy was the driving force behind advancements in trigonometry. Most of the early advancements in trigonometry were in spherical trigonometry mostly because of its application to astronomy. The three main figures that we know of in the development of Greek trigonometry are Hipparchus, Menelaus, and Ptolomy. There were likely other contributors but over time their works have been loss and their names have been forgotten. "Even if he did not invent it, Hipparchus is the first person of whose systematic use of trigonometry we have documentary evidence." (Heath 257) Some historians go as far as to say that he invented trigonometry. Not much is known about the life of Hipp archus. It is believed that he was born at Nicaea in Bithynia. (Sarton 285) The town of Nicaea is now called Iznik and is situated in northwestern Turkey. Founded in the 4th century BC, Nicaea lies on the eastern shore of Lake Iznik. He is one of the g reatest astronomers of all time. We know from Ptolemy's references that he made astronomical observations from 161 to 127 BC. (Sarton 285) Unfortunately, nearly all of his works are lost, and all that remains is his commentary on the Phainomena of Eudoxos of Cnidos, and a commentary on an astronomical poem by Aratos of Soloi.

Extractions: During these times people fought for pure survival and were no longer interested in a calendar that accurately kept track of time. According to the Yuga cycle theory of ancient India ( www.thegreatyear.com After the calendar reform of 1582 CE the days of the months were now counted in a cycle of 365.2425 days instead of 365.25 days. While the 4th of October 1582 was still the same day for both the Julian and the so-called Gregorian calendar, the next day (October 5th Julian) became October 15th in the Gregorian calendar. This reformation ensured that for the next 3320 years the spring equinox will be celebrated on March 21st, just as it occurred in the century before the year 325 CE when the Fathers of the Church discussed their Easter problem at the Council of Nicaea. This implies that one could use the Gregorian or our modern civil calendar, which is almost identical to the duration of the tropical year, to go back and forth in time by thousands of years and the equinoxes will remain within a day on or around March 21st and September 21st, and the solstices on or around June 21st and December 21st. So far so good, except that historians and astronomers still prefer to use the Julian calendar, projected backwards, to express dates in history as the inexact leap day system of a 365.25-day calendar avoids some of the complexities of the modern civil calendar. Nowadays, there are a number of computer programs available that make the conversion between the different calendars quite easy. For instance, if we have a June 21st 3420 BCE (Gregorian), it would correspond to the day July 19, 3421 BCE (Julian). Since the Julian calendar does not include the year 0, the year 1 BCE is followed by the year 1 CE, which makes it somewhat awkward for arithmetic calculations. Instead of using BCE dates, astronomers usually write the year 1 BCE as year while the year -100 corresponds to 101 BCE, etc.

Alexandria, Egypt, c. 370 ce , d. Alexandria, 415] Hypatia was a Greek philosopher and the daughter of another philosopher, Theon of Alexandria, who taught her mathematics. About 400 ce she became head of the Platonist school at Alexandria, where she lectured on the philosophy known as Neoplatonism. This combined Plato's ideas with a mix of Christian, Jewish, and East Asian influences and emphasized striving for an unreachable ultimate reality. Her edition of Euclid's Elements, prepared with her father, became the basis for all later versions. Christians deemed her philosophical views pagan and killed her during antipagan riots.

Extractions: In the four hundred and fifteenth year of the Common Era, in the city of Alexandria, a tragedy occurred that, according to those who write history, was so insignificant it has barely rated a mention in even the most extensive of historical records. However, this event was not only tragic for the individuals involved, but has had far-reaching consequences for anyone who has ever valued the importance of intellectual freedom and scientific enquiry. Hypatia of Alexandria, a mathematician, was dragged from her carriage and savagely murdered by a Christian mob in 415CE. She is perhaps better remembered for how she died rather than the way in which she lived. However, Hypatia lived an extraordinary life as the pre-eminent mathematician, philosopher, astronomer and astrologer of her time. It is not surprising that we have very little knowledge of Hypatia's life. Even in the early fifth century, Christian historians had achieved predominance and it is unlikely that they would have wanted to consign knowledge of this tragedy to history. She was a strong supporter of free enquiry and her murder is believed by many to symbolise the end of an era of intellectual freedom. Margaret Wertheim, in her excellent book '
Extractions: One topic that is sure to cause controversy amongst astrologers is that of whether the Tropical or Sidereal zodiac is most effective in practice. A recent forum debate revealed how passionately astrologers cling to alternate views. In 1997 the Traditional Astrologer magazine asked two expert astrologers to justify their own choice by reference to history, philosophical logic and the results of their own experience. Their responses have been reproduced here and allow us to consider the historical influences upon this 'astrological complication' in-depth. This debate assumes a knowledge of the issues connected to precession. For a more detailed explanation of precession and the early refinement of zodiacal signs refer to the article Heavenly Imprints In recent years certain astrologers have made two assertions that I would like to examine and, hopefully, refute. The first is that ancient astrologers used a sidereal zodiac; the second is that this, if true, implies that we should adopt one. The best answer to the assertion that the ancient zodiac was sidereal is a question: which zodiac? The zodiac was involved in chronometry, astronomy, and divination. These make conflicting demands, for chronometry implies a tropical zodiac but astronomy a sidereal one! Reconstructing the history of the zodiac is not easy - only a fraction of ancient writings have survived and 90% of Mesopotamian texts still lie unpublished in museum basements - but the following account is probably not too far from the truth.
